After ten seconds, the display will change to show

for five seconds,
the current passenger's set temperature setting and
an arrow for five seconds and
the automatic air delivery mode and fan speed.

the same when AUTO is pressed, the temperature

conditioning compressor on and
off.
%
(Air Conditioning Off): When you turn the air
conditioning off, this symbol will appear on the display.
When air conditioning is selected or in AUTO mode,
the system will run the air conditioning automatically to
cool and dehumidify the air entering the vehicle. If
you select
A/C
off while in front defrost or defog, the
A/C
off symbol will flash to let you know this is not
allowed. This is to prevent fogging.
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time
it
takes for
your vehicle to cool down. Then keep your windows
closed for the air conditioner to work its best.
On cool, but sunny days while using manual operation
of the automatic system, use bi-level to deliver warm
air to the floor and cooler air to the instrument
panel outlets. To warm or cool the air delivered, turn the
temperature knob to the desired setting.
In AUTO mode the system will cool and dehumidify the
air inside the vehicle. Also while in AUTO mode, the
system will maximize its performance by using
recirculation as necessary.
